I'm in Connecticut and there is no way I would let any dealership near me touch my Cat. The Dodge/Jeep guys are pathetic and I have had very little positive experiences at any dealership service center in my area.
I'm surprised that you would let a dealership do the warranty work. I would let them diagnose it, at most, then buy the parts and have my real mechanic do the work. I called FCA to confirm this was okay, and they said yes, but I would have to come out of pocket and wait for a reimbursement check.
Dealerships should employ specialty mechanics so enthusiasts can pay a premium for a higher end mechanic rather than forcing us to either cringe everytime we walk into a dealerships service center, or lose us a customer, which in my case they have, and my local Indy gets all the work.
